I'm hoping you might be able to help me on a good cause. I'm an art director for an ad agency and we're working on an idea for an ad for WWF, addressing the problems of global warming and the impact on the habitats of polar bears.

We are looking for images of sleeping or lying polar bears that photographers are willing to donate. Unfortunately there is no budget for this ad, as is often the case with charity ads, so we are looking for good willed individuals who want to help us on a really important cause.

If you are interested in donating this image or any others you may have of polar bears, please get in touch. My email is:
